On Enter key not executing the menu item function

[Navyasri-K]

Angular version: 5
ContextMenu version: 5.0.3
public onContextMenu(contextMenu, contextMenuService, $event: KeyboardEvent, item: any, index): void {

contextMenuService.show.next({
  contextMenu: contextMenu,
  event: $event,
  item: item
});

$event.preventDefault();
$event.stopPropagation();

}

When enter click on selected menu item. it is not executing the function. Tried to debug with Package code.

ContextMenuContentComponent.prototype.keyboardMenuItemSelect = /**
* @param {?=} event
* @return {?}
*/
function (event) {
console.log('Raised event')
if (!this.isLeaf) {
return;
}
this.cancelEvent(event);
this.menuItems[this._keyManager.activeItemIndex]; always getting -1 and activeItem as undefined
if (menuItem) {
this.onMenuItemSelect(menuItem, event);
}
};
